Stable subgroups in graph products

Stable subgroups of finitely generated groups were introduced by Durham and Taylor as a generalisation of the quasiconvex subgroups of hyperbolic groups. They also nicely coincide with many other classes of subgroups: in the general case they are the hyperbolic Morse subgroups, in mapping class groups they are the convex cocompact subgroups, and in right-angled Artin groups they are the purely loxodromic subgroups. In this talk we will extend this to a characterisation of the stable subgroups of graph products with infinite vertex groups. This is joint work with Sahana Balasubramanya, Marissa Chesser, Johanna Mangahas, and Marie Trin.
